What is the correct term for “mince pies”? [closed]

They are called mince-pies (at least the ones with a top on for Christmas)

The fruit stuff is called mincemeat, originally it contained meat with fruit and spices. Then just the suet (meat fat) with the fruit - but is still called mincemeat.

The "minced fruit" is presumably a supermarket avoiding customers getting confused about whether it's meat or fruit.

This term is a contraction of minced meat to mincemeat as the original pies contained meat minced or chopped finely and cooked with fruit, nuts and spices in pastry. The pastry would have been in pie form with a top. A tart is the same as a pie but without the top.

From OED:

a. Meat cut up or ground into very small pieces.

b. The mixture of currants, raisins, sugar, suet, apples, almonds, candied peel, spices, etc., and originally meat chopped small, typically baked in pastry, as in mince pies and other traditional Christmas dishes. Cf. minced meat n.

Mincemeat contains suet and nuts, minced fruit is just that without suet and nuts etc.
